I want to tell my experience with OSH Park.I placed my first order some weeks ago. Flow for ordering is very easy and straightforward. Before placing the order you can see from your personal area the rendered board with all layers (silkscreen, top copper, bottom copper, holes, etc.). If you live outside US, shipment is First Class Mail FREE! Yes, FREE!I received the boards after 10 days. When I opened the package, I realized why so many people are happy with this service. Boards are made in the US and are exceptionally HIGH quality. Perfect silkscreen, soldermask and hole plating. OSH Park has definitely become my ultimate and only PCB manufacturer. Do not trust all that chinese stuff.

Never designed my own PCB, always used proto boards. Decided it was time to get a real PCB fabricated. Made a small, multi purpose Arduino Uno shield. got three beautiful purple boards with gold plated pads for $28.50 and paid $5 more for priority shipping(total 33.50).

If you have never had a PCB fabricated I really recommend doing it at least once. it is extremely worth it to pay just to have a professional looking board.

ive ordered about 10 times from them for small boards both thru and surface mount. not one problem but besides the quality product it should be noted the quality customer service. the best period, of any industry. the cable companies should take a page for oshparks customer service playbook.

besides a great product, customer service contacted me after i asked about doing a run for possible sales. not only did they answer my question, they contacted me with advice and pointers, gave me a few hints on eaglecad, and went above and beyond what customer support is there for.

I've ordered many different designs from OSH Park. If you're not in hurry and if you live in Europe, shipping costs are unbeatable for small boards and small quantities (shipping is free!).If you need 2 oz copper or ENIG finish, also the fabrication costs are almost unbeatable. All their PCB were exactly as ordered, and they show you the "as fabricated" image before you place the order.

I've done about a dozen different boards with OSH Park, and I recently needed to do a board with plated slots and a panelized approach with complicated shapes nested together. After reading their guidelines for making slots (which is well written), I submitted a ticket with OSH to make sure that my design would get fabricated correctly. Jenner got back to me quickly, and gave me some suggestions for improving my layout to make it more likely to be fabricated properly. He and the other OSH support staff helped me numerous times and even bumped up my order to a quick-turn to ensure that I would get the boards on time. I've recommended OSH to others, and everyone I know who's used them has had a great experience.

I won't reiterate all the good things already said (which are true), but I will add that of all the cheap fabs out there they are the only ones who give you a lead-free finish (ENIG no less!) and high Tg (170C) FR4 boards suitable for lead-free reflow temperatures. If you are not mass producing or reselling then that may not matter. But if you are, watch the other guys price jump when you check those options!

For smaller boards they are hard to beat even if you don't need the lead-free stuff.

I've used OSH Park several times. Mixed results. They are good for smaller, low power stuff if you're ok with long turnaround times.

Cons:Their production and USPS shipping combo is super slow, around 6 weeks to Canada. Even won a free "express service" and it took 5 weeks to get the boards in.Copper electroplating is very thin, no good for higher currents, vias have high impedance. Hole sizes wrong on a couple orders, rounded down=too small and I was offered free re-do. Isopropyl alcohol cleaning the PCB attacks the solder mask. Dark purple mask is hard to see traces. Larger boards quickly get very expensive.

Ordered standard 2-layer design. Silkscreen is amazing. Submission is completely automated. They don't offer many options, they have only one color for silkscreen / PCB. They only offer one thickness (1.6mm) and have only one finish (ENIG). Minimums are 6mil track + 6mil spacing.Timeline:- Order placed Saturday morning- 24h after order the board was assigned to a panel- 51h after order the board was sent to fab for production- 10 days after order the board was received by OSH Park from & shipped to me- 12 days after order I received the boards

They ship from south of Portland via USPS First Class Package with tracking.

I sent the exact same four-layer GERBER package to five different board houses: iTead, smart-prototyping, shenzen2u, seeed studio, and OSH Park.

The iTead and OSH Park boards both came out fantastic; these two fabs are clearly the leaders in quality. Both have outstanding above-expectations copper etch. iTead's is ever-so-slightly-better which lets you bend/break some of their design rules, but if you stick to the rules strictly then you can consider OSH Park and iTead basically equivalent. OSH Park advertises 5mil/5mil for the outer layers; iTead advertises 6/6 but they'll let you get away with 5/5 if you don't do it in too many places. iTead's ENIG gold layer is a bit thicker.

The main differences between iTead and OSH Park are the silkscreen, soldermask, and board routing.

OSH Park's silkscreen is totally amazing quality -- it's a production-quality silkscreen like you see on the Arduino boards. Really really beautiful. Not sure that matters for prototype boards, but it's cool. For comparison iTead's silkscreen is digiprint -- not pretty, but it's functional which is what matters for protoboards.

OSH Park also seems to have slightly better soldermask registration, although it's hard to be sure since I only got three boards (iTead sent me 10). The best-registered iTead soldermask is about the same as the OSH Park boards, but some of the iTead boards had registration significantly worse than OSH Park. Again, hard to be sure since I only have three data points for OSH Park.

Finally, OSH Park leaves the break-away "wings" on your boards. Of course it's no trouble to break them off yourself, but then you've got those ugly rough edges that you have to manually mill down... kind of a drag. Yeah, I know I'm being picky here. iTead mills down the edges before they ship your boards.

Turn-around time is basically the same to the US, which is a bit baffling. Both boards got to me 11 days after the GERBER was approved. I think OSH Park is really missing a huge opportunity to grab a big chunk of business from the Chinese fabs here... the main disadvantage of ordering from China is the 4-5 day shipping delay. If OSH Park would run a panel as often as the Chinese houses do they'd have a 2x turnaround-time advantage and would totally crush all of them. I don't understand why they don't do this.

I have had multiple very small prototypes made at OSHPark.The finish is good and every run has been of equal quality.They have always responded to my support inquiries within 24h.Also when looking into pricing keep in mind that at their price all boards are ENIG finish, which almost doubles prices on small runs at every other providers.

I will most definately continue to use them for prototyping on small boards.
